"This book outlines medical experimentation that was conducted by Unit 731, heinous acts including injecting human subjects with pathogens; monitoring the progress of diseases by drawing blood samples from and conducting vivisection on live individuals; exposing human subjects to infected insects in an open-air testing field; infecting a health individual with venereal disease by way of forced sexual intercourse with a carrier of venereal disease; causing frostbite on limbs by exposing them to water and cold air in a sub-zero temperature environment; and collecting human specimens-organs, body parts and even entire bodies of human subjects-which were subsequently kept at Unit 731’s lab and the army medical facilities in Tokyo. None of the subjects in Unit 731’s custody survived the war, as they either died during experiments or were killed en masse as part of the Japanese cover-up effort at the war’s end. Some of the biological weapons thus developed, meanwhile, were put to use during the Japanese military campaigns against China. The Imperial Japanese Army also set up other medical units in Beijing, Nanjing, Guangzhou, and Singapore, so that biological weapons research and development could be carried forth in the broader region of Asia and the Pacific under Japanese military control."
